How resistant are turned edge trays to moisture, heat, or other environmental factors?

The resistance of turned edge trays to moisture, heat, or other environmental factors can vary depending on the materials used in their construction and any additional treatments applied. Here's a breakdown:

Moisture Resistance: Turned edge trays can be engineered with varying levels of resistance to moisture, depending on the materials chosen and the application of protective coatings. Laminated paperboard, commonly used in turned edge tray construction, inherently offers a higher degree of moisture resistance compared to standard paperboard due to its layered structure. We apply specialized coatings such as aqueous or UV coatings, which create a barrier against moisture infiltration. These coatings effectively seal the surface of the tray, reducing the risk of water absorption and potential damage to the contents. While turned edge trays with enhanced moisture resistance are suitable for environments with occasional exposure to moisture, it's important to note that they may not be entirely impervious to water. Prolonged exposure or immersion in liquids can compromise the integrity of the trays over time, emphasizing the importance of selecting the appropriate level of moisture resistance based on the intended use case.

Heat Resistance: Turned edge trays exhibit a moderate level of heat resistance, although their tolerance to high temperatures depends on the specific materials employed in their construction. Paperboard-based turned edge trays can withstand typical ambient temperatures encountered during storage and transportation. However, prolonged exposure to elevated temperatures can lead to thermal deformation or warping of the trays, affecting their structural integrity and aesthetic appearance. These coatings act as a protective barrier, minimizing heat transfer and mitigating the adverse effects of thermal exposure. While turned edge trays with enhanced heat resistance are suitable for applications where temperature fluctuations are a concern, users should exercise caution to avoid subjecting them to extreme heat sources that could compromise their performance.

Other Environmental Factors: In addition to moisture and heat, turned edge trays may encounter various other environmental factors that can impact their durability and longevity. Ultraviolet (UV) radiation from sunlight, for example, can accelerate the degradation of exposed surfaces, leading to fading or discoloration of printed graphics and materials. To address this, manufacturers may offer UV-resistant coatings or utilize UV-stable materials in the construction of turned edge trays. These protective measures help preserve the visual appeal and functional integrity of the trays when exposed to outdoor or well-lit indoor environments. Factors such as air quality, humidity levels, and mechanical stress during handling and transportation can influence the overall performance of turned edge trays. While turned edge trays are designed to withstand typical environmental conditions, users should consider the specific challenges posed by their operating environment and select trays with appropriate protective features to ensure optimal performance and longevity.
